Abstract

La présente invention a pour objet un mécanisme d'articulation en rotule entre une bielle (1) et au moins un palier (3, 3'). Une pièce de protection latérale (12, 12') interposée entre la bielle (1) et le palier (3, 3') est agencée en anneau monobloc comprenant un organe d'usure (14, 14') et un organe de fixation (15, 15') solidaires l'un de l'autre. L'organe de fixation (15, 15') est en matériau dur et est interposé en serrage axial entre le palier (3, 3') et un épaulement (20, 20') d'un axe d'assemblage (7) entre la bielle (1) et le palier (3, 3'), par l'intermédiaire de ses faces d'extrémité opposées entre lesquelles est ménagée une réserve de réception de l'organe d'usure (14, 14'). Application à un mécanisme de commande de vol pour giravion, pour provoquer une variation du pas des pales d'une voilure tournante que comporte un rotor équipant le giravion.
